I have some weird things going on with my TRG and the contessa pic rail. Mounted it about 1.5 years ago with screws and blue loctite. For some time, after shooting the rifle hot some how loctite seeped into the chamber. Usually just whiped everything off and went on. A few days ago it happened again after a long time and decided that I would clean out all of the loctite and remount everything. After doing so, my zero shifted 0.2mrad up and 1mrad left at 100 meters. Was kinda surprised about the amount of windage shift. My ocd kicked in and redid everything. This time my elevation shift went back up to normal, but windage shifted again 1mrad left.
Both times shot a group at 100 and 300 meters, and the rifle holds still an amazing group and its zero and there is no weird alignment issues, ie no windage shift at 300m compared to 100m.
Im just super weirded out about the amount of windage shift and especially since it shifted 1mrad left both times so it has shifted a total of 2mrad left from original mounting. Is this in the normal parameters? Everytime mounted the rail with the first screw infront, and the rear most screw in the back to align the rail, and proceed to tighten the rest.
